In between Christina Applegate's inspired hosting performance and some seriously funny Dane Cook and Arianna Huffington impersonations, electro-poppers Passion Pit made their debut on SNL last nght with a thoroughly danceable pair of tracks from their recent LP, Gossamer. The group kicked things off with the wistful "Take a Walk" and closed out the show with sweet party anthem "Carried Away." Both cuts were crowd favorites during Passion Pit's festival run over the summer, and their energy translated well on the late-night stage.
